Most people who start with OpenERP doesn't make the right set-up of the software. Because of the wrong set-up the systems often reacts with errors and long trace backs.
Those starters are by definition not experienced. So they don't understand what the trace back is trying to tell them.
A lot of more experienced users have also their problems in interpreting the trace backs.
Next step for both categories is to post the trace-backs on the forum with their cry for help. If this happens it pollutes our nice forum.
Is it an idea to make some kind of a guide: "How to read your trace back yourself". If one can read is self one can communicate more effective on this forum. I am not experienced enought to make such a guide. But I hope your answers will be a start.
